I recently attended the Chicago Symphony Brass concert this past week. I was blown away by the performance, but was very confused when the principle trumpet player brought out an instrument I had never seen before. It looked like a small french horn, but had a sound between a trumpet and cornet. I have look all over the net and can't find what instrument this might be. I know that it is in the trumpet family, but that is the extent of my knowledge. Can anyone help me out?
